This new bad pixel table with USEAFTER of May 14, 2024 was generated using data taken from May 15, 2024, through June 15, 2024. Currently, the Calibration Reference Data System only has WFC3 UVIS bad pixel reference tables up to a USEAFTER date of April 01, 2024. The automated pipeline should now use this reference file as the bad pixel table on any UVIS datasets obtained between the dates above, or beyond because it represents the most accurate measure of pixel stability at the time of the science observation. These WFC3 UVIS bad pixel files were generated using 900 second dark exposures from the HST 31 daily monitoring programs 17345 and 17348. More information about the UVIS bad pixel tables is outlined in the WFC3 ISR 2018.15 and WFC3 ISR 2021.14. |

The ACS WFC bias, dark, CTE dark, and sink files were generated following the ACS WFC anneal on July 8, 2024, and should be used to calibrate ACS WFC observations taken between June 14, 2024 and July 8, 2024. |

Update to the COS NUV TDSTAB reference file for all modes, obtained using Python analysis scripts analyze_files.py, analysize_data.ipynb. A wavelength dependence was introduced to all supported modes and slopes were updated to model data up to August 2023. The file was tested by comparing all TDS observations since May 2009 to a reference model and by comparing NUV TA observations since September 2013 to remove sensitivity loss over time. The reference file has a USEAFTER date of 2009 May 11, the start of COS NUV operations. |
